What is an Anode Rod?

An anode rod is a key component in your hot water heater. It helps prevent corrosion and keeps your heater functioning as it should. Riverside, CA residents come to depend on their hot water heater without giving it a lot of attention, and the anode rod helps ensure that it does its job without trouble. But anode rods need to be periodically replaced, which is why a good maintenance service can be your best friend. Here’s a breakdown of what anode rods are and why they need to be periodically replaced.

Doing the Dirty Work of Collecting Corrosion

Anode rods are fairly simple objects: rods made of aluminum or magnesium surrounding a core of steel. Both of those metals are less “noble” than steel, which means if you put them in water alongside a piece of steel, they’ll corrode before it does. You can see the advantages right away. As long as the rod is corroding and falling apart, the same thing won’t happen to the sides of your tank. Rust will stay out of your water, and you’ll never develop a leak: both of which demand a significant repair bill to correct.

Corrosion Can Wear It Down

Of course, as the anode rod attracts all that corrosion, it will gradually wear down until only the steel core remains. When that happens, the walls of the water heater tank will become vulnerable. You can prevent it by replacing the anode rod when it starts to wear down: usually every five years or so, but sometimes more often depending on the specifics of your water heater. You can include anode rod inspection and replacement as part of a regular maintenance call from a qualified professional, making the task easy and stress-free.
